You need to choose between two telephone plans for local calls. Plan A charges $25 per month for unlimited calls. Plan B has a monthly fee of $13 with a charge of $0.06 per local call. How many local telephone calls in a month make Plan A the better deal?

If you set up an equation like this you can find the total number of calls you can make equal to Plan A:
25=13+0.06x
12=0.06x
200=x
So, you can make 200 calls for $25, which is equal to Plan A. So, if you make more than 200 calls a month, it makes Plan A a better deal. :o)
